Good posture supports your spine, so your spine can better support your body. The "core" muscles of your trunk are strengthened with good posture, allowing you to twist, turn, bend, run, jump and walk without needless strain or sprain injuries. Also, you can make your body shape look much better than if you stand and walk correctly. Correct posture is also a real help when it comes to slimming down and staying slim.

So that you'r spine can twist and move an allows your body to do the same.
Radial and rotation actions of the body are done by the thoracic and lumbar spine.

There are two main principles for getting good posture. 1. Practice correct posture in everyday activities: standing, sitting, laying, bending and walking. 2. A balanced exercise program that strengthens both antagonist and protagonist muscles. For example, if you do sit-ups to strengthen your stomach muscles you must do equal conditioning of the lower back (antagonist muscles). If you do not do this your body will become out of balance and you will develop poor posture. The fundamentals of good posture are a "straight" back and keeping your center of gravity over the load bearing joints, shoulders, hips, knees and ankles. For in depth information refer to "8 Steps to a Pain-Free Back" by Esther Gokhale, L.Ac. and "The Pain-Free Program" by Carey, Anthony M.A., C.S.C.S.. Both are excellent sources that teach how to develop good posture.
This means that your lumbar spine is mildly curved in an S shape, but the individual vertebrae are still aligned properly. The preserved vertebral alignment suggests that the curvature is not severe enough to cause misalignment of the vertebrae. Treatment options may include physical therapy to strengthen the muscles supporting the spine and improve posture.
Are we talking about long fluorescent "tubes"?The socket may be bad, or the tube is not seated correctly in it's socket.Some fixtures use a socket that the tubes "twist" into.Twist the tube slightly in either direction until it seems "seated".
in the medical world, dextro is a synonym for right. dorsal refers to the parts of the spine that are facing out (the little knobby bumps that run down everyone's back) as opposed to the part of the spine that is facing inwards towards your organs. its just like a dolphin or shark- their dorsal fin is on their back.
Scoliosis refers to an abnormal twisting of the spine. Rather than being in perfect alignment, the vertebrae are sometimes out of alignment relative to the vertebrae above and below them. When the vertebrae of the thoracic spine - the middle section of the spine where the ribs attach - can be seen to progressively twist to the left, the condition is called levoscoliosis.
